Description

Technical Field

[0001] The present invention relates to the technical field of material transportation and lifting, in particular to a material lifting conveyor device. Background Art

[0002] The material lifting and conveying device is a feeding mechanism that replaces manual labor and is used in many fields. In granaries, the application of lifting conveyors is more widespread and common. In the granary, the staff will place the high end of the lifting conveyor above the transport bucket. When in use, the staff will continuously put grain materials onto the conveyor belt at the lower end of the conveyor, which can greatly improve work efficiency.

[0003] In the existing field of grain crop lifting conveyors, the most common model is a conveying device that uses a conveyor belt as the carrying medium. The conveyor belt conveyor is suitable for the efficient transmission of bagged or large-volume grain crops due to its stable and reliable performance. In specific use, it is also necessary to transport bulk crops, such as soybeans and wheat. After the staff put the bulk crops on the conveyor belt, due to the limited height of the anti-slip raised patterns on the conveyor belt, the granular crops cannot be piled up too much during the transportation process, which will cause rolling and scattering of the crops, making them difficult to clean.

[0004] To this end, we propose a material lifting conveyor device. Summary of the Invention

[0005] A technical problem to be solved by the present invention is that when existing conveyor belt conveying mechanisms are used to convey granular crops, due to the limited height of the anti-slip ridges on the conveyor belt, the granular crops cannot be piled up too much during the conveying process, and will roll off, causing the crops to be scattered everywhere and difficult to clean.

[0006] In order to solve the above technical problems, an embodiment of the present application provides a material lifting conveyor device, including a support frame, symmetrically distributed mounting side plates are arranged on the support frame, two driving rollers are rotatably connected between the two mounting side plates, the driving rollers are located at the ends of the mounting side plates, and a No. 1 motor for driving the driving rollers is arranged on the mounting side plates; a conveyor belt body is sleeved on the driving roller, and the conveyor belt body moves and operates through the two driving rollers; a plurality of equally spaced grooves are opened on the outer surface of the conveyor belt body, and the conveyor belt body can be bent at the grooves; and a bending mechanism is also included, which is arranged on the mounting side plates and connected to the conveyor belt body, and is used for bending and deforming the conveyor belt body.

[0007] In some embodiments, a second guide rail is provided on the symmetrical surfaces of the two mounting side panels.

[0008] In some embodiments, a plurality of connecting plates are provided on the inner ring of the conveyor belt body, which are vertically aligned with the cutting grooves respectively. Guide rollers are provided on the connecting plates. The guide rollers are located in the No. 2 guide rail and can roll along the No. 2 guide rail.

[0009] In some embodiments, a guide rail No. 1 is further provided on the symmetrical surface of the mounting side panel, and the guide rail No. 1 is located below the guide rail No. 2. An entrance track and an exit track are respectively provided at both ends of the guide rail No. 1, and the entrance track is provided at the near-ground end of the mounting side panel, and the exit track is provided at the far-ground end of the mounting side panel. The guide roller can move from the entrance track to the guide rail No. 1, and from the exit track to the guide rail No. 2.

[0010] In some embodiments, the bending mechanism includes a No. 2 motor arranged on the outside of the mounting side plate, and a cutout is opened on the inner wall of the mounting side plate close to the entrance track. The drive shaft of the No. 2 motor extends into the cutout and is connected to a pulley group. A gear connected to the pulley group is provided in the cutout. A movable plate is provided on the mounting side plate, and one end face of the movable plate is adapted to the entrance track. A toothed plate meshing with the gear is provided on the movable plate. The movable plate can be moved vertically by the gear, and the movable plate can respectively fit with the groove walls of the No. 2 guide rail and the entrance track.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1:

[0036] See also Figures 1-9 The technical solution provided by the present invention is: a material lifting conveyor device, including a support frame 1, symmetrically distributed mounting side plates 2 are arranged on the support frame 1, two driving rollers 8 are rotatably connected between the two mounting side plates 2, the driving roller 8 is located at the end of the mounting side plate 2, and a No. 1 motor 5 for driving the driving roller 8 is provided on the mounting side plate 2; a conveyor belt body 3 is sleeved on the driving roller 8, and the conveyor belt body 3 is moved by the two driving rollers 8; a plurality of equally spaced grooves 4 are opened on the outer surface of the conveyor belt body 3, and the conveyor belt body 3 can be bent at the grooves 4; and a bending mechanism 601 is also included, which is arranged on the mounting side plate 2 and connected to the conveyor belt body 3, and is used to bend and deform the conveyor belt body 3.

[0037] In the embodiment, the conveyor belt body 3 at the groove 4 has a strong deformability and is easy to bend, and also has an auxiliary effect of increasing friction and reducing material falling.

[0038] like Figure 4 and Figure 5 As shown, a second guide rail 16 is provided on the symmetrical surfaces of the two mounting side panels 2 , and the second guide rail 16 is designed along the outer shape of the mounting side panels 2 .

[0039] like Figure 2 、 Figure 3 and Figure 5 As shown, the inner ring of the conveyor belt body 3 is provided with a plurality of connecting plates 13 which are respectively vertically aligned with the cutting grooves 4, and a guide roller 14 is provided on the connecting plate 13. The guide roller 14 is located in the No. 2 guide rail 16 and can roll along the No. 2 guide rail 16. The guide roller 14 is provided at the edge of the conveyor belt body 3, at both ends away from the driving roller 8. During normal use, the guide roller 14 and the driving roller 8 do not contact each other.

[0040] like Figure 4 、 Figure 5 、 Figure 8 and Figure 9 As shown, a guide rail No. 15 is also provided on the symmetrical surface of the mounting side panel 2. The guide rail No. 15 is located below the guide rail No. 2 16. An entrance track 22 and an exit track 27 are respectively provided at both ends of the guide rail No. 15. The entrance track 22 is provided at the near-ground end of the mounting side panel 2, and the exit track 27 is provided at the far-ground end of the mounting side panel 2. The guide roller 14 can move from the entrance track 22 to the guide rail No. 15, and move from the exit track 27 to the guide rail No. 2 16.

[0041] In the embodiment, when the guide roller 14 in the No. 1 guide rail 15 moves to the exit track 27, it will gradually enter the No. 2 guide rail 16, so that the conveyor belt body 3 is gradually converted to a flush state, allowing the conveyed material to be unloaded.

[0042] like Figure 5 、 Figure 8 and Figure 9 As shown, the bending mechanism 601 includes a second motor 6 arranged outside the mounting side plate 2, and a single chip microcomputer connected to the second motor 6 is provided on the mounting side plate 2 for controlling the operation or stop of the second motor 6;

[0043] The single chip microcomputer is set with three sets of thresholds, one for the conveyor belt 3 to run flat, the second for the conveyor belt 3 to run in a V-shaped state, and the third for the conveyor belt 3 to run in an inverted trapezoidal state;

[0044] A cutout 17 is provided on the inner wall of the mounting side panel 2 and close to the entrance track 22. The driving shaft of the No. 2 motor 6 extends into the cutout 17 and is connected to a pulley group 19. The No. 2 motor 6 has the function of forward and reverse operation. A gear 21 connected to the pulley group 19 is provided in the cutout 17. A movable plate 23 is provided on the mounting side panel 2. One end face of the movable plate 23 is adapted to the entrance track 22. A toothed plate 26 meshing with the gear 21 is provided on the movable plate 23. The movable plate 23 can be vertically moved by the gear 21. The movable plate 23 can be respectively fitted with the groove walls of the No. 2 guide rail 16 and the entrance track 22. The setting of the cutout 17 enables the pulley group 19 and the gear 21 to be embedded in the installation, thereby avoiding obstruction to the normal movement of the guide roller 14 and ensuring the normal operation of the guide roller 14.

[0045] like Figure 5 、 Figure 8 and Figure 9 As shown, two limit columns 24 are provided on the inner wall of the mounting side panel 2, and a limit groove 25 matching the limit columns 24 is provided on the movable panel 23. The movable panel 23 is slidably connected with the limit columns 24. The limit columns 24 and the limit grooves 25 can limit the range of motion of the movable panel 23, and the two limit columns 24 can prevent the movable panel 23 from generating unnecessary rotation when being driven by the gear 21, making it impossible to move normally.

[0046] In the embodiment, when the No. 2 motor 6 is started, it drives the gear 21 through the pulley set 19, and the gear 21 moves the movable plate 23 in the groove through the tooth plate 26, so that the movable plate 23 moves to the top surface and fits with the groove wall of the No. 2 guide rail 16, or moves the movable plate 23 to the bottom surface and fits with the groove wall of the No. 1 guide rail 15, thereby opening or closing the No. 2 guide rail 16 and the No. 1 guide rail 15.

[0047] like Figure 5 and Figure 8 As shown, a reserved plate 18 is provided on the mounting side plate 2, the reserved plate 18 is located on one side of the cut-out 17 and can be fitted and connected with the movable plate 23, the reserved plate 18 has a partition and limiting function, a No. 1 pressure sensor is provided on the reserved plate 18, a No. 2 pressure sensor is provided in the No. 1 guide rail 15, the No. 2 pressure sensor is provided directly below the pulley group 19 and the gear 21, the No. 1 pressure sensor and the No. 2 pressure sensor can both contact the guide roller 14, the pressure sensor is connected to the single-chip microcomputer provided on the outer wall of the mounting side plate 2, thereby preventing the guide roller 14 from moving down into the cut-out 17 when moving, forcing the guide roller 14 to move in the No. 2 guide rail 16.

[0048] In the embodiment, during normal use, the movable plate 23 fits against the wall of the entrance track 22 . At this time, the top surface of the movable plate 23 is flush with the top surface of the reserved plate 18 , and the guide roller 14 can pass smoothly.

[0049] In some embodiments, during tiling operation, when the guide rollers 14 pass the pressure sensor, the single chip microcomputer does not start the second motor 6, so that the multiple sets of guide rollers 14 all move in the second guide rail 16;

[0050] When the V-shaped state is in operation, when the first set of guide rollers 14 passes the No. 1 pressure sensor, the single chip microcomputer starts the No. 2 motor 6 to rotate forward to move the movable plate 23 upward and open the entrance track 22. The second set of guide rollers 14 then follows the entrance track 22 and enters the No. 1 guide rail 15. When the second set of guide rollers 14 passes the No. 2 pressure sensor, the single chip microcomputer starts the No. 2 motor 6 to rotate backward to move the movable plate 23 downward and close the entrance track 22. The third set of guide rollers 14 then moves in the No. 2 guide rail 16, thus achieving the V-shaped state.

[0051] When the inverted trapezoidal state is running, the threshold setting value of the single chip microcomputer has changed. When the first group of guide rollers 14 passes the No. 1 pressure sensor, the single chip microcomputer starts the No. 2 motor 6 to rotate forward to move the movable plate 23 up and open the entrance track 22. The second group of guide rollers 14 then follows the entrance track 22 into the No. 1 guide rail 15. When the second group of guide rollers 14 passes the No. 2 pressure sensor, the single chip microcomputer does not start the No. 2 motor 6. After the third group of guide rollers 14 passes the No. 2 pressure sensor for the second time, the single chip microcomputer starts the No. 2 motor 6 to rotate in the opposite direction to move the movable plate 23 down. The fourth group of guide rollers 14 then moves in the No. 2 guide rail 16 to realize the inverted trapezoidal state.

[0052] like Figure 5 and Figure 8 As shown, a blocking plate 20 is provided on the movable plate 23. The blocking plate 20 can be flush with the groove surface of the first guide rail 15. The blocking plate 20 has a limiting function to prevent tension from forcing the guide roller 14 to move upward, affecting normal operation;

[0053] The connecting length between the blocking plate 20 and the movable plate 23 is much shorter than the distance between two adjacent guide rollers 14 .

[0054] Recombination Figure 1 In the embodiment, when the No. 2 motor 6 rotates forward and drives the pulley group 19, the gear 21 drives the No. 2 guide rail 16 to move upward, thereby making the blocking plate 20 flush with the groove surface of the No. 1 guide rail 15, and the guide roller 14 can move from the entrance track 22 to the No. 1 guide rail 15.

[0055] like Figure 1 and Figure 2As shown, an extension plate 7 is provided near the middle of the two mounting side plates 2, and a support plate 9 is further provided between the two mounting side plates 2. An electric push rod 10 is installed on the support plate 9, and a mounting frame 11 is fixed to the output end of the electric push rod 10. A compensation roller 12 that fits the conveyor belt body 3 is rotatably connected to the mounting frame 11. The compensation roller 12 can be moved by the electric push rod 10. The electric push rod 10 and the compensation roller 12 can make the conveyor belt body 3 taut.

[0056] In the embodiment, when the electric push rod 10 is started to extend, the compensation roller 12 is forced to push the conveyor belt 3 by pushing the mounting frame 11, so that the conveyor belt 3 is tightened, which is beneficial to the normal operation of the conveyor belt 3 and avoids being too loose to be able to transport.

[0057] Example 2:

[0058] See also Figure 10-11 The technical solution provided by the present invention is as follows: the limiting column 24 is fixed on the movable plate 23, the limiting groove 25 is opened on the installation side plate 2, the limiting column 24 passes through the limiting groove 25 and is slidably connected with the limiting groove 25, and a limiting plate with a diameter larger than the limiting groove 25 is provided at the end of the limiting column 24 to prevent the limiting column 24 from escaping from the limiting groove 25.

[0059] In the embodiment, when the movable plate 23 moves, the staff can observe the movement of the limit column 24 to determine the open or closed state of the entrance track 22, which is conducive to the leveling and resetting of the conveyor belt body 3 after use. During use, the movement of the movable plate 23 and the operation of the movable plate 23 can be observed in real time, so that problems can be discovered and handled in time in the event of damage, which is highly practical.

[0060] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0061] While the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions, and alterations can be made to the embodiments without departing from the principles and spirit of the invention.
